Aluminum is a Multipurpose Metal

By: Harry Browar

Aluminum is the most multipurpose metals that we have today. It is a silvery and ductile. It is a good conductor of heat and electricity. The greatest quality of aluminum is that it is extremely light in weight and does not get corroded easily. When aluminum comes in contact with oxygen it reacts to form a very thin layer of oxide, which prevents the aluminum from weathering. Polished aluminum is more refelective than most metals except for silver gold and copper. Aluminum is extracted from Bauxite ore by the process of electrolysis.

One of the many uses of alluminum are mirrors. Because it has one of the highest reflective properties of all metals, it is used widely for mirrors and telescopes. A thin sheet of the metal is placed behind float glass to make household mirrors. In telescopes the sheet of alluminum is placed in front of the glass for added reflection and magnification.

In today's world alloys of aluminum are more in use. The alloys of aluminum are strong and lightweight and are perfect for making rocket and aircraft gears, which need to be durable and featherweight. These alloys are stronger than pure aluminum but have a reduced amount of anti decay properties. If you want maximum anti corrosion you have to use aluminum in a pure form. Aluminum in pure form is also used as protective varnish.

Another use of alluminum is for killing bacteria in water and making it safe to drink. This is alluminum in a powder form. When used for this pupose it is known as allum. It can also be used to kill some parasites that can cause diseases in fish.

Most electrical wires are made of aluminum, as it is very cost effective. Even though copper is a safer metal, people opt for aluminum to save money. Since aluminum is a very good conductor of heat and electricity, people do not find aluminum a safe metal for electrical purposes in many countries, due to the risk of over heating.

You can use powdered aluminum in paints and it has proved especially good for a wood primer because as it dries it becomes water resistant. Aluminum is used to put in a silvery hue to paints and add a silvery touch to mirrors. Silvering process adds a thin film of aluminum oxide at the back of the mirror. In this process the glass is placed in a heated chamber along with aluminum and after that it is exposed to oxygen. In the original process silver was used for this use.

Permanent magnets are made from aluminum alloys called Alnico alloys. To make Alnico magnet you have to heat aluminum to a certain temperature then cool it in a magnetic field. Alnico magnets have wide usages in making electrical gadgets.

Aluminum as mentioned earlier is one of the most versatile metals ever. The Chinese first started its use around 300 AD. Greeks and Romans also used it for dying purposes.
